T0 all whom t may concern lie it known that we, Farmers X. CLARK, J r., and FRANCIS X. CLARK, Sr., citizens ot the United States, residing` at the city of St. Louis, State of Missouri, have invented a certain new and useful improvement in Rollllaper Cores, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and. use the same, reiference being had to the accompanying drawings, forming part oitl this specification, in which- Figure 1 is a perspective view oli' a roll paper core of our improved construction. ll`ig. Q is a sectional view oi a roll of' paper in position on a lfixture and which roll of paper is equipped with our improved core.

Our invention relates to a new and useful core for roll paper such as is used for wrapping purposes and in printing presses of the rotary web type, the principal object ot our invention being to provide a comparatively simple inexpensive core which may loe readily placed in position in the opening through the center of a roll ot paper, and which core supports the roll without binding effect on the innermost layers of the roll of paper and permits all of the paper to be unwound while in comparatively smooth condition.

A further object of our invention is to provide a roll paper core comprising a pair of elongated tubular members which gradually taper toward their inner' or meeting ends, and by thus gradually tapering the members forming the core, the same can be readily used with rolls of paper which vary in width.

llt is the present practice to drive tapered wooden plugs into the ends of the opening through the center of a roll of paper, which plugs form bearings for the spindle used in supporting the roll in its fixture and these wooden plugs when placed in position exert a wedging effect on the innermost layers or windings of the roll et paper, and in some instances the ends oi.3 the innermost layers or windings are crushed or torn so that the inner end of the roll is uniit for use.

l/Ve propose to overcome the objections just noted by providing a core formed et two elongated tubular members of sheet metal which, when in use, support the innermost layers of the roll of paper in such a man ner that the entire roll can be readilyr unwound and used for wrapping purposes.

To the alcove purposes our invention consists in certain novel features ot construe-- tion and arrangement ot' parts hereinafter more tully described and claimed.

As shown in the accompanying drawing our improved core consists of a pair oi' tiixbular members 10 and 11 preferably formed of sheet metal and tapering gradually from their outer toward their inner ends. The inner end of the member 11 is provided with a tubular socket 12, which is adapted to receive the straight tubular inner end 13 et the member 10 when the parts are properly assembled in a roll of paper. The outer ends oft the members 10 and 11 are flanged outwardly as designated by 14, and xed to said flanged outer ends in any suitable manner are disks 15 with which. are formed integral inwardly projectingu collars 16. These collars ferm bearings tor the usual spindle 1'? which extends through the core and the ends of which bear in the .brackets or fixture 18 which supports the roll on a sheli or counter.

The use oi? our improved core is apparent and to position. the same in a roll or' paper it is only necessary to insert the members 10 and 11 in the ends et the opening througi the roll. and manipulate said members so that the tubular end 13 is seated in the bearing 12. The spindle 17 is new positioned in the collars 1G at the ends oi the members 10 and 11 and the roll now ready to be mounted in its supporting VFixture. llhe taper oi' the members 10 and 11 is very slight so there is little or no wedging action oi'f said members against the innermost layers of the roll oi' paper when the core is positioned therein.

By gradually tapering the members 10 and 11. toward their inner or meeting ends it is possible to utilize one of the cores in connection with rolls of paper which vary in width, it being understood, oi course, that when the core is positioned in a roll of paper which is conuiaratively narrow in width the end portions ot the members 10 and 11 will project slightly beyond the ends oi the roll.

A core of our improved construction is comparatively simple, can. be cheapiy pro duced, is readily positioned in the roll of paper and supports the same, in a substantial manner on the spindle of the iiXture. lVe have shown and described our improved core as used in connection With a roll of Wrapping paper, but it will be readily understood that the core can be made of considerable length and of heavy material so as to be positioned in the large rolls of paper used in printing presses of the rotary web type.

lt will be readily understood that mino-r changes in the size, form and construction of the various parts of our improved core can be made and substituted for those herein shown and described Without departing from the spirit of our invention, the scope of which is set forth in the appended claims.

Vle claim:

l. A roll paper core comprising a pair of tapered cylindrical members, the inner ends of which are adapted to engage each other when the core is positioned for use in a roll of paper.

2. A roll paper core comprising' a pair of tapered cylindrical members, the inner ends of which are adapted to engage each other When the core is positioned for use in a roll of paper, and bearings formed in the Outer ends of said members, which bearings are adapted to receive a supporting spindle.

3. A roll paper core comprising a pair of tapered cylindrical members, the inner ends of which are adapted to engage each other When the core is positioned for use in a roll ont paper, iianges on the outer ends of said members, and bearings formed in the outer ends of said members, which bearings are adapted to receive a supporting spindle.

4C. A roll paper core comprising a pair ot tapered tubular members provided With bearings at their vouter ends, and with straight tubular portions on their inner ends, one of which tubular port-ions telescopes the other When the core is positioned in a roll of paper.

A roll paper core comprising a pair of tapered cylindrical members provided at their inner ends with straight tubular sockets, the socket at the inner end of one of which members is adapted to telescope the socket end of the opposite member When said members are positioned in a roll of paper.

G. A roll paper core comprising a pair of tapered cylindrical members, the inner end of one of which members is adapted to telescope the inner end of the opposite member When said members are positioned in a roll of paper, and bearings formed in the outer ends of said members, which bearings are adapted to receive a supporting spindle.

T. A roll paper core comprising a pair of tubular members Which gradually taper from their outer toward their inner ends, the inner end of one of said members being adapted to telescope the inner end of the opposite member when said members are positioned in a roll of paper, and flanges on the outer ends of said tubular members.

8. A roll paper core comprising a pair of tubular members which gradually taper from their outer toward their inner ends, the inner end of one ot said members being adapted to telescope the inner end of the opposite member when said members are positioned in a roll of paper, and bearings formed in the outer ends of said tubular members.
